Constructor & Destructor Documentation

HeatEqBoundaryConvection::HeatEqBoundaryConvection

(

)

Class constructor.

Creates a convection boundary conditions class, the constructor specifies the type as "convection". It also sets h_constant and Tinf_constant to zero.

Member Function Documentation

Number HeatEqBoundaryConvection::h	(	const Point &	p,
		const Real	t
	)		[virtual]

A virtual function for returning the convection term, h.

By default this function returns a constant value defined in the h_constant attribute. If constant h is to be used then only h_constant must be changed (it is zero by default). To create a non-constant h a derived class should be created that inherts this class. This h() function should then be defined in this new class to return the desired value.

Reimplemented from SlaughterFEM::HeatEqBoundaryBase.

Number HeatEqBoundaryConvection::Tinf	(	const Point &	p,
		const Real	t
	)		[virtual]

A virtual function for returning the convection term, Tinf.

By default this function returns a constant value defined in the Tinf_constant attribute. If constant Tinf is to be used then only Tinf_constant must be changed (it is zero by default). To create a non-constant Tinf a derived class should be created that inherts this class. This Tinf() function should then be defined in this new class to return the desired value.

Reimplemented from SlaughterFEM::HeatEqBoundaryBase.

virtual void SlaughterFEM::HeatEqBoundaryConvection::value	(	DenseVector< Number > &	output,
		const Point &	p,
		const Real	t
	)		[inline, protected, virtual]

Computes and returns the convective term.

This returns the convective term ( \(h \cdot T_{\infty}\)) value that is computed by the h and Tinf functions that may be customized. This member is used by the HeatEq class thus is protected.

Parameters:

output	A reference to the vector that stores the stores the computed flux
p	A libMesh point
t	The time
